Authorities have identified a man found dead in Linn County that led to an all-day standoff with police.

The body of Gregory William O'Hare, 47, of Cedar Rapids, was found in a road Friday morning after a call from a neighbor. Deputies soon realized that a suspect was in a nearby home, but the man would not come out.

A SWAT team was summoned and tear gas used to get the man out. Officers used a stun gun to subdue the man, identified as Martin Paul Wilkinson, 63, once he came out of the house.

Police took Wilkinson to a hospital for treatment of injuries and arrested him.

An autopsy is being conducted to determine the cause of O'Hare's death.
